SPECIFICATION forming part of Letters ?atent N0. 442,946, dated.Deeember 16, 1890. Applioation fi1ed July 29 1890. SerialNo.3602&(Nomodel.)

T0 all whom it may concern:

Be it known that we, JOHN L. BOTTORFF and OHARLEY A. CONYERS, b0thresidents of Union Star, in the county of DeKalb and State of Missouri,have invented cerbain new and usefulImprovementsin Oorn-Cultivators; andwe do hereby declare that the following is a f u11, dem, and exactdescription 0f the inventi0n, whieh Will en ab1e others ski1led in theart t0 which it appertains 130 make and use the same, reference beingha.d to the acconnpanying drawings, which forn1 a part 0f thisspecification.

Ou1 invention rel-ates t0 in1provements in corn-cultivators, Lhe objecbbeing t0 provide a cheap, simple, and effective apparatus f0r eutting 0xdestroying the weeds an l other injurions growt-h between the rows andturning over the seil upon the growing corn in such quantities as may bedesired.

The invention consists in the novel feutures 0f const-ruction and newcombinations 0f parts, hereinafter fully described, und definite1ypointed 0ut in the c1aim.

In the accoxnpanying dmwings, Figure 1 represents a plan view of acorncultivator constructed in accordance with 0u1 in vention. Fig. 2is acentral sectional view of the szu ne. Fig. 3 is an end view.

In the said drawings, the reference-n un1eral 1 designares the s'1depieces 0E the imnroved eultivator composed of metal bars hzwing theirfronts and bottomsfonnerl with cut-tingedges.

2 designates the front cross-lmrconnecting the front end 0f said sidepieces, and to which thewhiffletree 01 other devices which connect withehe harnoss 0f' the dmft-animals zue (3011- nected. Seeured to thisplate or bar 2 is a segment 3, having mekteeth 3, the rem end 0f saidsegment being conneoted Witl1 rear connecting-ba-r 1.

Intermediate 0f the 0r0ss pieces 01 bars 2 and 1 and supp0rted byuprights5 is the drivers seab 6, and pivoted in lugs 7 0n the frontconnecting-pieee is a1ever 8 Wihin convenient mach 0f the driver,provided with a pivoted pawl 9, which engages With 1bhe teeth in thesaid segment, said lever being conneeted by means 0f bar 01 10 1 10 withLhe earth-turning disks, hereinafter described. At the forward ends 0fthe side pieces 1 me forn1ed 01 provided the outwardly exteuding curvedrod 10.

cutting knives 01 blades 12, which serve 0 eut ohe weeds between therows 01": corn. Se-

cured to the rea.r' connecting piece 01 bar 4: and projecting rearwardlyare tw0 zmns 16, having sorew-threaded apertures a1; their rear ends,within which work the serew-threaded vertieal rods 01 standards 11,carrying at their lower endsinwardlyturned lugs, upon whieh arepivotally secnred rhe rouary disks 15. These disks 2we made of metal andconeavw convex in form, the concave portions facing each other. At theirnpper ends the standards 11 are provided with rigidinwardly-projecringarnns 13, connected together ab their innet ends and pivotally conneetedwith the The rods 01 standards 11 a1e vertica1ly ad j ustab1e in thearnas 16, so as t0 regu- 1ate the height Of the disks.

The operation Will be readily understood. The apparatus is designed tostmddle the rows 0f 00111 with the knives 01 blades and disks 011 eaehs'1de 0f the same, and when drawn over the field said knives 01 bladesWill cut the weeds between the rows, while the disks Will turn the earthnpon the rows. These disks can oe oscillated 01 inclined so as to turnup ehe earth more 01 lass, according to requirements, by means of the1eve1 S, 0011- necting-rod 10, arn1s 1G, und rods 14:, Whi0h a1eoscillated. t0 vary such inc1ination.

Having; thus described our invention, what we claim is In acorn-cultivator, the combination, with the side pieces 1 and front anc1rem eonnecting-pieees, of the curved euting-blades 12, the segment 3,With teeth 3", the lever 8, having pawl 9, the rearwardly-extendingarn1s 90 16, having screw-threaded apertures, the vertically-adjustablerotary 10ds 14, earrying ab their lower ends the concavo-convex disks 15and a1: their upper ends 1ahe inwardly-projecting arms 13, and the 10d10, connecting said 95 arms With (110 1ever 8, substantially as de,-scribed.

In testirnony that we c1aixn the foregoing as our own we have hereuntoaffixed 0ur signatures in presenee of two witnesses.
